About this map

Dunnigan Hills dominate the western portion of this Yolo County landscape, rising sharply from the Sacramento Valley floor. The settlement of Zamora sits at a critical junction where the valley's flat agricultural plains meet these uplands, served by a network of drainage and irrigation systems essential to the region's productivity. The Tehama Colusa Canal and the Colusa Basin Drainage Canal are prominent features that illustrate the intensive water management required in the Central Valley.

Several distinct valleys, including Bird Valley and Oat Valley, are carved into the hills, providing natural corridors through the terrain. These areas are drained by seasonal watercourses like Willow Spring Cr and Bretona Cr, which flow toward the lower basin. To the southwest, the curiously named Hungry Hollow lies near the Goodnow Slough, marking the transition into the broader agricultural expanse. The map detail highlights the intersection of natural topography and large-scale water engineering in modern California.
